COUNTERPOISE
A brass balance where the scale physically is the equals sign. Hang mass until the arm sits level, and the equality stops being a symbol you read and becomes a thing you did with your hands.
Equality & algebra
The pack suggests age 6 and up. The difficulty itself follows the player, not the age.
